The Washington Nationals and free agent left-handed pitcher Oliver Perez have agreed on a two-year, $7 million contract. The 34-year-old started the 2015 campaign with the Diamondbacks, who sent him to the Astros in a mid-season deal. Perez appeared in 70 games total, all out of the bullpen, finishing the season with a 2-4 record, a 4.17 ERA, a 3.30 FIP, 51 strikeouts, and 15 walks in 41 innings.
From 2006-2010, Perez appeared in 101 games for the Mets, starting all but 10 of them, going 29-29 with a 4.71 ERA and a 5.01 FIP. Control problems and injuries derailed Perez's later years with the Mets; the southpaw allowed an MLB-high 105 walks in 2008, then made just 31 appearances between 2009 and 2010 due to lingering patellar tendinitis in his right knee and leg. The Mets released Perez before the 2011 season despite $12 million remaining on a three-year, $36 million contract signed before the 2009 season.
